Q:i trying to make a solar panel. right now i dont have money to go and buy a copper sheet. so can i make it out of aluminum foil. if there is a way please tell me how. and what do i use for wires. i making this to charge batteries.
Presumably you plan to create a focused parabolic reflector and have it oriented to heat the bottom of a pan. It will obviously need to be larger than the pan in order to gather sunlight outside of the pan's shadow, as well as gather and concentrate enough light onto the bottom of the pan to heat its contents. If you use black paint on the bottom of the pan, make sure it's high temperature paint (available at auto supply stores, often used to paint engine blocks and exhaust manifolds). Yes, a cover on the pan will make it hotter.
Q:Can solar panels be used in areas with high pollution levels?
Yes, solar panels can be used in areas with high pollution levels. While pollution may slightly reduce the efficiency of solar panels by blocking some sunlight, they can still generate electricity. In fact, using solar panels in such areas can be beneficial as they provide a clean and renewable energy source, helping to reduce reliance on polluting fossil fuels.
Q:Can solar panels be installed on a pergola or shade structure?
Yes, solar panels can be installed on a pergola or shade structure. In fact, installing solar panels on a pergola or shade structure can provide both shade and renewable energy generation, making it a practical and efficient solution for maximizing space and reducing energy costs.
Q:What is the efficiency of solar panels?
The efficiency of solar panels refers to how effectively they convert sunlight into usable electricity. Generally, the efficiency of solar panels ranges from 15 to 20 percent, with some advanced models achieving efficiencies of up to 23 percent. However, it's important to note that the efficiency can vary depending on various factors such as the type of panel, its age, location, and environmental conditions.
Q:Please tell me what they are made of and how the materials help the solar cell produce electricity. Im doing a science projects so i need help on knowing all this info. Its a debate, so i need correct information please.I will please need more information about the bad things about solar energy and solar panels. Please say what solar panels do to create pollution or do anything that is not friendly to the environment. If you want just give me a website. Thank you
A okorder /, or resistance—vary when light is incident upon it) which, when exposed to light, can generate and support an electric current without being attached to any external voltage source, but do require an external load for power consumption.
Q:Can solar panels be used in areas with frequent thunderstorms?
Yes, solar panels can be used in areas with frequent thunderstorms. While thunderstorms may temporarily reduce the efficiency of solar panels due to cloud cover and reduced sunlight, they do not pose any significant risk to the panels themselves. Properly installed solar panels are designed to withstand various weather conditions, including thunderstorms. Additionally, the energy produced by solar panels during sunny periods can still offset the electricity consumed during stormy periods, making them a viable option for areas prone to thunderstorms.
Q:Can I add more solar panel let say up to 200 watt and adding two 2 volts battery using the same charges controller and power inverter?
That charge controller is notoriously cheap and burns up easily. If you are going add solar panels, also buy another charge controller to go with them. They can both be connected to the same battery bank. I don't believe the kit comes with batteries, so you would buy whatever size 2V battery bank your power requirements call for. The size of the inverter depends entirely on what you are going to power with it, not the size of the panel array. As long as you are not powering anything that is over the 300W rating, you don't need a new one. Just be sure to check the details of the inverter, is it 300W continuous, or can it handle up to a 300W surge? Also, it's a modified sine wave inverter instead of a pure sine wave inverter, so don't plug any sensitive electronics into it. They may not work, or you may get a buzz or hum from it.
Q:Installing solar panels requires a big initial investment. Before I make this investment I want to check to see if the money I will save by installing solar panels will actually pay for this investment, in the long run. To calculate my savings, we should consider the area (square feet) I currently have available to install solar panels. Look at the available sunlight and its intensity in my state each month of the year. Based on this data estimate how much energy my solar panel will generate. Then compare that with how much energy (kWh) I currently consume based on my electricity bill.
Your school spend $0,000 per month or per year?? Photovoltaic (Solar Panel) panels have a really large initial capital investment. If you live in a location (e.g. West Coast Desert, SoCal) where there are many sunny days so you might be able to break even quicker. Also note ,there are state and federal grants that can help ease the capital cost. Energy demand keeps going up so expect our current rates to double. People who have alternative forms like wind and solar will have the advantage when this time comes. Just think of when the US had it's oil crisis in summer of 2008, people with small efficient vehicles such as Prius's didn't feel the price increase like the people who bought cheaper large SUV's.
Q:I am looking at a need of roughly 30w/hour need per 24 hour period. I have spent several hours now looking for information online and have found plenty of info regarding the panels themselves, but information regarding the batteries backups have been slim. I understand that there is a 5-7 hour peak time to collect the energy. I am looking for information regarding the batteries themselves. How do the batteries work, what size batteries should I look for, and what is the life expectency for the batteries? Any website links would also be appreciated!
First, you didn't say the voltage. Second, 30 W/hour per day. Third, battery backup capacity in Ah = Ampere hour. For 2 Volt DC here's the calculations : 30 w/hour means = 0.83 or rounded Ampere hour. You know peak time 5-7 hour (let say 6 hour)charging time (collect the sun energy). Ampere hour per day (24 hour), with 20 Ah Battery backup is OK. And the Solar Panel is 3 Ampere charging capacity minimal = 3 Amp x 6 hour = 8 Amp hour.
Q:Can solar panels be installed on schools or universities?
Yes, solar panels can be installed on schools or universities. In fact, many educational institutions around the world are increasingly adopting solar energy systems to reduce their carbon footprint, lower energy costs, and provide hands-on learning opportunities for students about renewable energy. Installing solar panels on schools and universities can not only help them become more sustainable but also serve as a powerful educational tool for students and the broader community.
